Training eccentric viewing for mobility purposesPeople who have central scotomas (such as with macular degeneration) need to learn to use their preferred retinal locus to find things in the environment such as traffic signals, approaching vehicles, etc.
This page has a simple procedure for helping them learn to do that.

Self-Study Guide:
Preparing Visually Impaired Students for Uncontrolled CrossingsThis course, which is required by several O&M university programs, provides information needed to teach students to deal with uncontrolled crossings.
I just finished extensive revisions which I started last summer as a result of what I learned from developing a product for APH to help O&M instructors teach about these crossings -- the material has been simplified and organized
to flow in a more orderly manner, and videos and photos were added.

Example of Partial OcclusionShows a great example of using partial occlusion to help ensure that students can notice unexpected drop-offs when distracted with vision (scroll up the page to find out more about partial occlusion).

Video clip about traffic signalsA short clip from my videotape "Intersection Design and Street-Crossing Strategies for Blind Pedestrians: Then and Now" was posted as part of an NCHRP online workshop, and I posted a link to it.

Safely Experiencing Walking Without VisionHow can people safely experience what it's like to walk without vision if they don't know how to use a cane?

An Introduction to Orientation and Mobility is a special edition that I wrote for VisionAware, a newsletter of
the Associates for World Action in Rehabilitation and Education, published for people with low vision.
Since that time, the American Foundation for the Blind became the publisher of this newsletter and some of the articles I wrote were extensively revised, so AFB and I agreed that they would be listed as author rather than me.
